We're dividing 903591 by 58 
Our goal is to divide 903591 by 58.

Let's proceed to step 1:
58 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 58

Advancing to step 2:
The number 58 fits into 90 1 times, leaving a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 58 from 90 to get 32.
Bring next digit (3) of the dividend behind the 32 and repeat the process: 323 / 58

On to step 3:
The number 58 fits into 323 5 times, leaving a remainder of 33.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 33 after subtracting 290 from 323.
Append the next digit (5) from the dividend to 33 and continue with: 335 / 58

Going ahead to step 4:
If we divide 335 by 58, we get 5 and a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 155.0
If we subtract 290 from 335, we get 45.
Fetch the next digit (9) from the dividend, attach it to 45 and continue: 459 / 58

On to step 5:
The number 58 fits into 459 7 times, leaving a remainder of 53.
Record the quotient 7 as the next digit in the result. 
Result so far: 1557.0
If we subtract 406 from 459, we get 53.
Grab the next digit (1) from the dividend, add it to 53, then carry on: 531 / 58

Going ahead to step 6:
When dividing 531 by 58, we get 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 15579.0
The remainder is 9 after subtracting 522 from 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
If we divide 90 by 58, we get 1 and a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 15579.1
The remainder is 32 after subtracting 58 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 8:
58 can be fit into 320 5 times, resulting in a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 15579.15
Deduct 290 from 320 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 9:
300 divided by 58 is 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 15579.155
The remainder is 10 after subtracting 290 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 15579.155 with a remaining 0.001.
